ASHLAR-SETTING CLAMP.

Application filed January 22, 1926.

My invention relates to a device for setting facing stone or so-calledashlar-s in building walls or other structures and the object is toprovide a simple, efficient and inexpensive device for handling andsetting in place such slabs of stone.

In the accompanying drawing:

1 is a side elevation of my device in operative position to set a facingstone.

Fig. 2 is a right hand elevation of Fig. 1 showing the facing stone indotted lines only.

Referring to the drawing by reference numerals, 5 designates an ashlarof the usual quadrangular form. is the main or body member of my devicecomprising preferably a vertically disposed fiat, metal bar the lowerpart of which is adapted to engage one vertical face ot' the stone 5with its flat side and its lower extremity is extended at right angles,as 6, preferably in a widening wedge shape to form a tongue to engagethe lower edge of the slab. The bar 6 may be given a right angle twistabout as at 6' and its upper portion extended vertically as 6 and thenceangularly and upwardly in the same direction as tongue 6.

7 is a vertically adjustable, tiltable clamp member pivotally securedwith a bolt 8 in an aperture in the upper main bar section 6. The clampcomprises a flat vertically disposed wing with two horizontal rows ofapertures, an upper row 9 and lower row 10, registering vertically inpairs. The clamp comprises further an extension 11 of inverted L-shape,within the angle of which the upper edge and adjacent side of the slab 5are retained. When in this clamping position the bolt 8 partly holds theclamp rigid but I provide also a suitable pin 12 adapted to be insertedin hole below bolt 8 and thence through a register ing aperture 6 in bar6.

13 is a soft padding such as felt suitably secured to the inner angle ofclamp arm 11 and the upper surface of ledge 6 to contact directly withthe stone 5 and prevent scratching or highly polished surfaces.

The upper main bar arm 6 is provided with a suitable number of alignedaper- Serial No. 82,982.

tures 14. In one of these is inserted the hoolr 15 or other suitableengaging means of any hoisting apparatus (not shown). Thus when a slabis held in the manner shown in Fig. 1 it is simply lowered gradually andaccurately to its proper place, the lower ledge 6* merely making a smallindenture in the soft mortar and which is readily filled after removingmy device. The device is readily removed from the slab 5 by simplyremoving the pin 12, tilting the clamp member 7 until part 11 is raisedabout as to the position shown in dottedlines in Fig. l. The device isthen simply drawn away from the wall as toward the right from Fig. 1.

It will be readily understood that slabs of various thicknesses andwidths may be handled by simply changing the pivot bolt to requiredheight in bar section 6 and aligning as required any one of the holes 9with the hole 6 The use of my device has already been fully disclosed inthe foregoing specification.

.What I claim is:

1. An ashlar setting device comprising a vertically disposed suspensionbar the lower extremity of said bar directed at right angles to engagethe lower edge of an ashlar and the adjacent vertical part of the baradapted to bear against a face of the ashlar, the upper part of saidmain bar directed .angularly from its main vertical part toward the sameside as its lower extremity, a vertically and horizontally adjustablemember pivotally mounted intermediate the extremities of the bar andhaving an inverted L-shaped extension adapted to engage the upper edqeand adjacent face of the ashlar diagonally opposite to the parts engagedby the lower extremity of the bar, said angular upper end of thebar'adapted to be engaged by suitable hoisting means.

2. The structure specified in claim 1 in which said pivotal membercomprises a normally vertically disposed flat member with two horizontalrows of apertures arranged vertically in pairs said bar having avertical row of likewise spaced apertures, a pivot pin adapted to beinserted selectively in one of the upper apertures of the pivotalprovided with a number of apertures in member and an aperture in the barand a WhICh to engage the hoisting means se1ecreadily removable lockingpin insertible betively. 10 10W said pivot pin in ahgned apertures in Intestimony whereof I affix my si na- 5 the bar and the member. ture.

3. The structure specified in claim 1 in which said upper angular arm ofthe bar is DENNIS N. ANGEL.
